RAILWAY-SWITCH.

SPEGIFIGATION forming part of Letters Patent hie. 740,232, datedSeptember 29, 1903.

A nmim filed March 18, 1903.

To all whom it may concern: D

Be it known that I, THOMAS TIMOTHY CHAL- ONER, a citizen of the UnitedStates, and a resident of the city of New York, borough of Manhattan, inthe county and State of New York, have invented a new and ImprovedRailway-Switch, of which the following is a full, clear, and exactdescription;

This invention relates particularly to improvements in railway-switches,an object being to provide a switch of simple construction that may bereadily and positively shifted by a motorman or driver on a moving car.

I will describe a railway-switch embodying my invention, and then pointout the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification,

cate corresponding parts in both the figures.

Figure 1 is a plan view of a'switch mechanism embodying my invention,and Fig. 2 is a perspective View showing the free end of theswitch-tongue.

In the drawings, 1 2 designate the mainrails of a track, and 3 4: theswitch-rails. Mounted to swing at the end of the switchrail 3is aswitch-tongue 5, the point 6 of which is held yieldingly and normallyagainst the main rail 1, as here shown by means of a spring 7surrounding a rod 8, movable in a From the point end the tongue isprovided with an extension 10, which is curved slightly inward, and theupper surface of this extension is below the plane of the top surface ofthe switch point or tongue, thus permitting the flanges of thecar-Wheels to pass over said projection and onto the tonguewhen a car isto be runupon the switch. The switchtongue is movable on a plate 11,attached to the track-ties, and pivoted to this plate 11 is a shiftingdog12, which engages with the projection 10 at the side adjacent to therail 1. The top surface of this dog 12 is substantially on a plane withthe top surface of the projection 10.

The shifting device consists of a shoe 13, carried by a car. This shoeis pointed atits Serial 1%, 148,561. on model.)

end, and if it is desired to pass the car along the main track the saidshoe is lowered to engage with the dog 12, which will force theswitch-tongue out of engagement with the main rail, permitting the carto pass. If the car is coming from the opposite direction, it is obviousthat the flange of the wheel will swing the tongue inward against theresistance of the spring.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. Inarailway-switch,aswitch-tonguehaving anextension fromits point end, the top of said extension being below theplane of the top surfaceof the; tongue, and a swinging device at theside of the track-rail for engaging said extension.-

2. In a railway-switch, a switch-tongue yieldingly held against a mainrail, an extension from the point end of said tongue, the upper surfaceof said extension being be low the plane of the top of the tongue, and aswinging dog at the side of the-track-rail for engaging with saidextension.

3. In a railway-switch, a switch-tongue, a spring for holding the tongueyieldingly in connection with a main rail, an extension from the pointend of the tongue and below the plane of the top thereof, a pivoted dogfor engaging with said extension, and a device carried by a car forengaging with said dog to swing the tongue.

'45. In a railway-switch, a plate at one side of the track-rail, aswitch-tongue pivoted on said plate, a curved extension from the freeend of the tongue below the plane of the top thereof, a dog pivoted tosaid plate and engaging with said projection, and means for holding thetongue yieldingly against the rail.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses' THOMAS TIMOTHY CIIALONER.

FRANK J. KABSHICK, WILLIAM BARTON.
